Be it known that I, G AnLns'Moss, -a citizen of the United States, and a resident of the city of New York, county and State of New York,have invented certain newand" useful Improvements in Antislipping 'Attachments for Vehicle Wheels-of; which the following'isa description. i 7- The present invention relates to improve: ments in anti-slipping attachments for ve hicle wheels, 1311C]. particularlyisuch attaclr ments adapted to be engaged,withthetread of solid or pneumatic tires oi" anto-mobile wheels. 'An object ofthe invention is to provide in such an attachment ground engaging means which will engage the ground in'a manner to eitectually I prevent skidding o1 slipping without injury or excessive wear to the tire structure, and without injuiyto the street. To this end I propose to providein the present embodiment of the invention, a fiat ground engaging surface: and a fiat tire en a 'inm surface free from an obstructionto n e ent methods of manufactur sothat the same may be produced expeditiously in large quantities, with a high degreegof accuracy and uniformity, and at relatlvely small cost;

, It is a still further objectto provide an improved tightening and connection means which may be locked in closed position, and which may be operated with facility and will remain positively in closed. position during use without danger of accidental opening due to shocks or jars frorn t'heroad.

Ifurther propose vto provide novel means for maintaining the device'upon the tire in a snug manner, so that there will be no looseness, or rattling.=With these and other objects in view, embodiments vof my inventlon are shown in the accompanyingdrawings, and these embodiments willbe hereinafter more fully, set 'forth and eventually pointed outin theclaims. g Y L 1 In the -accompanying drawings;

ThetWo-block members-are spaced from each other formlng two points of support, and

both engaging flatly upon the ground, so

that a surface is providedz which will sub .stantially; supportthe tire, will not injure the streetyand Will, at the same time, e'ffectually resist slipping or skidding.

U-shaped link members 39 are provided at theends of the tread members,- the end portions being passed through slots 20 and 21, the transverse intermediate portion be ing bent into offset relation to the end portiofi as at 40, and seating in the pockets 23. Thus the link members do not form. an ob-v struction upon the innerside of the tread 4 memb eiyand lie snugly again'stthe si'de of 1 thetire at theirends. The endsofthelink membersare providedwith eyelets ll; and 42 engagedby a link member 43straight; its

intermediate portion, and provided at its endswith eyelets e4: and' l5 'engagedb-y the eyelets; at the''nds of similarly"formed link members 46, constituting; a circumferential chain'at each side of thetire interconnecting the several tread members which are dis posed in are;

ins,

Figure 6'," or the flat elongated links 47, Figure/7, may be provided betweenithetreadmembers; The, connection of the chains dis- 1 closed, with the treadmembers, is such that free-turning movement'of the chain is per mitted, and kinking of the chain is preventedpso that the same is always in condition to be immediately placed upon the tire Without having to untangle or, laboriously arrange the partsin proper position as they o' fjthemselves', Wil1iassume this position.

At one end of each of; the chains at each comprising a channeled member 49015 sheet inetalbent upon itself and an opposed channel member 50 also formed of sheet metal bent uponyitself and adapted to'fit inthe,

member 49 and pivotally connectedv thereto by a pin 5l, the member 49 beingprovided with: a pin;52,p assing through the link 48 c0n necting the device thereto. The side portions c of 'the 7 member- 491%1261 each provided With a pocket 53 inclinedfrom the edges of said side's away fro'm'thelink 48, the portion 54 at one side of the pocket being inthe form. of a hook 55 The member 50is provided with a cut-out 56' in each-- of its sides extending toward the pin 51 and 'havingits base substantiallyvregistering with a portion of the pocket 53,]its edge beingcurvedacross the pocket 53 in the closed positionof'the device to'close the-pocket, an enlarged portion 57 being disposedat the side of the pin 52, the end of the member 50 extending over-and away from the saidpin to form a lever handle portion 58. A lifting finger'po'rtion 59' of the member 5O eXtends along and slightly' beyond'thespaced portion of the-pocket 53 of the member 49.

- At the other ends ofeach-"ofthe chain members there is provided an elongated flat link 60 'adaptedito be lockingly engaged With the connection andtightening member.

-The operation of connecting the link at one end ofthe chain to the tightening and connection device; at the other end-consists in first placing the device-inopen position, as indicated in Figure 10; and hooking the link 60 over the member 50, so that it gen-c gages the" cut-out 56, and thereupon the member" is s ung'intoclosed position, the en larged portion 57' retainingthelink in place Withinthe cutout and forcing the same over.

the end of'the' hookportion- 55,-Whereuponit drops into the pocket-58, in which position it; is retained, it beingonly-possible to re- -move the same by-manual 'operation o-f the device. Anaperturefil is; provided in the end of the lever handleportion 5 8,-,and in order tolock the device so that the attachment may not be removed by unauthorized tion' indicated in Figure 8; in dotted? lines,

whereupon the pull'of the chain will overcome the slight resistance of the-hoo-lr portion 55 in-this position and-pull th'e portion 50 into ope-nposition: 7 i y In orderv 'tohold the attachment upon the tire tightly,andat the sametime yieldably,

so as to preventrattling-orlooseness, there are provided'at suitable intervals, helical" springs Ge -permanently "connected to-*one}-,of

the chainsb-y fi'guref8 shaped linkrmembers 65 and adapted to beplaced'transversely across the felly and'hookcd to the other chain by hooks 66. If desired the side chains may be made in two parts to be connected by hooks and eyes on the respective ends. This construction will facilitate the attachment to the wheel. These spring members are readily attached and detached, and when in place, will positivelymaintain their connection without danger of becoming accidentally disconnected. A piece of leather or other suitable protective material may, if desired, be placed beneath the springs to prevent injury to the felly.

In Figure 4 I have illustrated a slightly modified form of construction in which the side chains 67 are connected .to the'tread members by a pair of links 68 and 69, similar in construction to the U-shaped link 39 in the above-described form of construction, so that the side chains are at a point further removed from the-tread surface of the tire.

In Figure 5 I have illustrated a further modification especially desirable for pneumatic tires, in which the tread member is provided at each end of the flat intermediate portion with eyelets or loops 70 and 71, having flat elongated links 72 and 73 connected thereto, and which are connected to the side chains 74 and 75 by link connections 76 and 77 formed of strips of metal bent upon themselves to format each end, loops or eyelets 78 and 79, the end portions of the strip being riveted, as at 80, to the intermediate portion. The forms of construction shown in Figures 4 and 5 render the side portions of the tread members of great flexibility, and by providing additional links, the same may be made to fit any size of tire.

A single tread block 81 is provided having diagonal corrugations 82. It will be understood that this form of tread block may be employed in the other forms, and that in all the forms, several, that is, two or more, tread blocks may be employed. These blocks may, if desired, in some cases,be made integral with the tire engaging portion. By making the tread blocks of greater depth the same may be used for traction members to be used in snow or upon muddy roads.

In Figure 8 I have illustrated a modified form of device to be used in place of the lock 63, and which comprises a pin 88 having a head 84 at one end connected by a chain 85 to the link 46, and provided at its other end with a pivoted piece 86 adapted to be turned into transverse retaining position. a p

I have illustrated and described preferred the unitsupon the plate.

and satisfactory embodiments of my invention, but it is believed that changes may be made the ein within the spirit and scope said apertures to form recesses on the inner face of said tire-engaging member, and annuli on the outer face thereof, and tread means mounted upon said tire-engaging member between said flanges provided with apertures reamed at their ends and in alignment with said apertures of said tire-engag ng mem her, the reamed portions'at one end being I engaged by said annuli and rivet members engaged through sald apertures to secure saidtread means to said tire-engaging memher, the heads at one end of said rivetmembers being countersunk insaid recesses on the inner side of said tire-engaging member,; the heads at the other, ends thereof being countersunk in'said reamed portions at the,

exposed side of said treadjmeans.
